摘要

在这里，我们展示了一种新的方法来构建基于芘的、高效的、发红光的分子。两种合成的发光物质均表现出聚集诱导的增强发射（AIEE）特性和明显的机械致色行为，DCI-Py-1的蓝移（13 nm）和DCI-Py-2的红移（29 nm）。典型而罕见的λem = 686 nm的芘基红发分子为设计近红外芘基光电材料开辟了新的途径。进一步的研究表明，这两种材料都可以用于防伪邮票和指纹提取。

Pyrene-based, red-emitting, aggregation-induced emission luminogens: from structural construction to anti-counterfeiting applications†

Herein, we demonstrated a novel approach to construct pyrene-based, high-efficiency, red-emitting molecules. Both of the as-synthesized luminogens exhibited aggregation-induced enhanced emission (AIEE) properties and distinct mechanochromic behavior with a blue-shift for DCI-Py-1 (13 nm) and red-shift for DCI-Py-2 (29 nm). The typical, yet rare, pyrene-based, red-emitting molecules with λ_em = 686 nm open up new avenues to design near-infrared emitting pyrene-based photoelectric materials. Further studies revealed that both of these materials can be utilized for anti-counterfeiting stamps and fingerprint extraction.
